Hello, picked up a Les Lat/hybrid the other day. (thanks David). Played around with it and the edge off this is more jnat than coti! Did 100 strokes or so on a light slurry to water. My understanding is the abrasive on the hybrid side is at least partial quartz among others. This has the feel water only like a hard arkansas. Very hard stone. Yellow side is super fast with slurry and hybrid side is fast as well with yellow side of slurry stone. Im liking a zippy coti edge, but is it really a coti? I mean it is but are there garnets on the hybrid side? Either way Im a happy camper.
